Mastering Service Mesh: Enhance, secure, and observe cloud-native applications with Istio, Linkerd, and Consul (English Edition)

Understand how to use service mesh architecture to efficiently manage and safeguard microservices-based applications with the help of examples

Key Features

Manage your cloud-native applications easily using service mesh architecture

Learn about Istio, Linkerd, and Consul – the three primary open source service mesh providers

Explore tips, techniques, and best practices for building secure, high-performance microservices

Book Description

Although microservices-based applications support DevOps and continuous delivery, they can also add to the complexity of testing and observability. The implementation of a service mesh architecture, however, allows you to secure, manage, and scale your microservices more efficiently. With the help of practical examples, this book demonstrates how to install, configure, and deploy an efficient service mesh for microservices in a Kubernetes environment.

You'll get started with a hands-on introduction to the concepts of cloud-native application management and service mesh architecture, before learning how to build your own Kubernetes environment. While exploring later chapters, you'll get to grips with the three major service mesh providers: Istio, Linkerd, and Consul. You'll be able to identify their specific functionalities, from traffic management, security, and certificate authority through to sidecar injections and observability.

By the end of this book, you will have developed the skills you need to effectively manage modern microservices-based applications.
